Parachute (survival air guard)

ABSTRACT

The invention relates to a parachute (Survivial Air Guard), preferably applicable in an extreme life-threatening emergency situation. The parachute is particularly embodied as a round parachute and comprises a canopy which is connected to the parachute harness by means of several rigging lines. According to the invention, a parachute which opens quicker than conventional parachutes on usage in emergency situations may be achieved, whereby the canopy is provided with an unfurling and stablizing device for rapid unfurling and preferably stabilizing. The device is preferably fixed to the parachute, preferably within the parachute canopy, and preferably comprises a rapidly-inflating inflation system, preferably with gas generators, preferably airbag systems. In a further embodiment of the invention the parachute is integrated in a survival case.

The invention relates to a parachute (SURVIVAL-AIR-GUARD), preferably applicable in an extreme life-threatening emergency situation.

Its use should only occur when all previously known rescue methods and possibilities are no longer usable and/or are not available. Its use is intended, for example, especially in dangerous situations for people in skyscrapers, observation towers and similar buildings when all usual rescue contrivances and ways of escape down are no longer reachable and/or cut off. There are likewise widespread possibilities for application, for example for certain trade groups, in sports or in military areas. By itself, the special round canopy parachute (SURVIVAL-AIR-GUARD), preferably integrated in a survival case, because of a special design and construction offers multiple objective applications.

The parachute is specially-constructed as a round canopy parachute and displays a canopy that is joined with the parachute by means of several rigging lines.

A parachute that opens more rapidly than conventional parachutes in emergency situations is achieved in accordance with the invention in that the canopy is associated to an opening and stabilizing device for rapidly unfurling and preferably stabilizing the canopy. The device is associated with the parachute. The device is preferably attached to the parachute, preferably inside the parachute canopy, and preferably displays a rapidly inflating inflation system, preferably an air bag system.

Other advantageous features and embodiments of the invention are presented in the claims and in the following description.

The survival case (SURVIVAL CASE) 10 in accordance with FIG. 1 is, in practice, made of a light metal (aluminum) or of a suitable synthetic (e.g. polycarbonate, carbon fiber), and divided into three compartments 11, 12, 13 which, in the stand-by condition, are provided with lids 14, 15, 16 or closure caps, preferably covers, preferably locked. These are equipped with easily operable hinged locks or functionally comparable locking elements 17. Placed in these compartments 11, 12, 13 are all tools and equipment required for an extreme emergency at a great height, arranged in the order corresponding to the rescue procedure. The case 10 is additionally equipped with rollers 18 as well as with a displaceable (movable, adjustable) grip system 19.

Provided are a left (13), a center (12) and an outer (11) compartment. According to FIG. 2, located in compartment 11 is a commercial breathing device (oxygen breathing device) 20 consisting of a breathing regulator 21, breathing mask 22 or breathing mouthpiece. Nose clips or mouth/nose breathing masks, oxygen bottle 23, preferably 300 bar composite bottles with a harness system 24 for changing out the air bottle are accommodated. Also selectably capable of being employed are other breathing devices that are usual as in the mining industry or the navy, for example.

The center compartment 12 (see FIG. 19) displays a carrier frame 120 to which is attached the vest 71 (see FIG. 13). The carrier frame 120 is made of aluminum or carbon fiber and displays a top and bottom support, respectively 121, 122, which are joined via brackets 124 with attaching rails 125, preferably screwed on. The attaching rails 125 are preferably integrated in the case walls 11 a or 13 a, preferably injected. Furthermore, the supports 121, 122 are bowed in the support area 126 corresponding to the shape of the back, and are joined together by two spacers 127. The carrier frame 120 with vest 72 and parachute 30 in the stand-by condition are tightly locked/covered by the covers 15 a, 15 b, whereby the covers 15 a, 15 b are joined/held (together) with the case parts 11 and 12 respectively and/or with the carrier frame 120 by means of connectors not represented in any further detail.

Located in the center compartment 12, which in the stand-by condition is closed and in use is open at the back, front and top, is a so-called round canopy special parachute (SURVIVAL-AIR-GUARD) 30 with a rapidly inflatable opening and stabilizing system 31 based on the air bag system in automobile safety technology, which inflates the parachute in briefest time and keeps it stable in its prescribed form against application of external force, for example impacts against a solid partition, wall or other obstacles, so that it does not lose its efficacy and, by the more rapid opening with the aid of the more rapidly inflating and stabilizing system 31, its functionality is also achieved sooner than in the case of customary and known parachutes.

This rapid opening and stabilizing effect of the special parachute, which displays a canopy that is connected with the parachute harness 70 by means of several rigging lines 112, is achieved by the fact that associated with the canopy 35 is an opening and stabilizing device 31 rapidly unfurling and preferably stabilizing the canopy. The device 31 is attached to the parachute 30, preferably inside the parachute canopy 35, and preferably displays a rapidly inflatable inflation system, preferably with gas generators, preferably an air bag system.

In one form of embodiment of the invention according to FIG. 3, worked into the so-called round-canopy special parachute (SURVIVAL-AIR-GUARD) 30 at the periphery is a ring-shaped hose 31 that is connected at the center 32 of the parachute canopy 35 with six or even more radially disposed channels 33. These channels 33 are collected together or, to be precise, joined at the center 32 and equipped with an accommodating flange for a so-called gas generator, as is customary in motor vehicle safety technology with the known air bag systems.

Connected to this accommodating flange is a suitable gas generator, for example a gas-driven generator from the company Welz lndustrieprodukte GmbH, in Fellbach, having the license number D-ZLS DEKRA 001/00, helium sealed, approval number 9959, which, after ignition by electronic or mechanical means, fills the channel and ring system within the range of milliseconds with a gas that is not harmful to humans, and rapidly opens the special parachute (SURVIVAL-AIR-GUARD) and maintains it in its basic shape. Here the radially disposed channels 33 as well as the ring hose 31 made of gas-impermeable material that is mounted on the external diameter are made such that the degree of filling of the stabilizing system achieves an as great as possible service life. The hoses and channels preferably stitched of silicone or air bag fabric are made gas tight in the area of the stitched longitudinal seams by over-expanding the hose or the channels, e.g. with 3 bar. The expanded and thereby self slightly-opening seam area is completely filled with silicone and sealed. After relaxing the seam area and drawing together of the seam area, this latter is gas tight. Another advantageous embodiment of the hoses or channels consists in that they are woven round and, thereby, consist of round-woven hose and therewith display no longitudinal seams that have to be sealed.

The stabilizing ring hose 31 joined to the outer diameter 34 of the round canopy special parachute (SURVIVAL-AIR-GUARD) 30 is geometrically embodied such that the outer diameter 34 of the parachute canopy 35 is greater than the inner diameter 36 of the stabilizing hose (see FIG. 4). Achieved by this is that the rescue parachute (SURVIVAL-AIR-GUARD) when contacting obstacles does not become caught and slides off better.

As protection against damage by unknown external influences or also for better sliding off at obstacles, e.g. projections 37 on buildings 38 (see FIG. 5) also additionally capable of being installed on the surface of the parachute outer diameter is a suitable, smooth and rip-fast reinforcing strap 39, preferably reinforced parachute silk or air bag fabric. In addition, form stability of the parachute can also be stabilized with so-called rebound straps.

Alternatively, according to FIGS. 6 and 7, rapid inflation and stiffening of the round canopy special parachute (SURVIVAL-AIR-GUARD) can also be accomplished with more than one stabilizing ring, whereby then the channels going toward the center can be omitted and the stabilizing ring hoses 40, 41 arranged one above the other can each be filled by means of one or even more gas generators. Here it is also possible, for example, to use per hose ring two 42, 43, and 44, 45 respectively or more gas generators for filling one hose ring, which also can be ignited in time-delayed fashion. Time-delayed ignition of the gas generators also applies for all gas generators of all additional stabilizing rings.

When using two gas generators per hose ring, the two gas generators 42, 43, and 44, 45 respectively are appropriately oppositely disposed 180° from one another on the periphery (see FIG. 7) in order to equalize the reaction forces.

When using four gas generators 46 to 49 per hose ring (see FIG. 8), the four gas generators are appropriately disposed on the periphery at 0°, 90°, 180° and 270° in order to equalize the reaction forces.

In the case of this advantageous embodiment of the invention, according to FIG. 8 each of the hose segments 50 to 53 are connected together via sleeve joints 54 into which are also connected gas generators 46 to 49. Illustrated in FIG. 9 is the detail “A” of FIG. 8 in an enlarged representation.

FIG. 10 shows the sleeve joint 54 in cross section, whereby the joint 54 displays a formed part 55 with compression grooves 56 in which a thread 57 is provided for attachment of the gas generator 47. A silicone sealing sleeve 58 with retaining and compression edges 60 is pushed on over the formed part 55, also over the sealing sleeve 58 the hose segments 51 and 52, and over this a protection and compression sleeve 61 made of aluminum, whereby, self-understood, are provided in the sleeves 58 and 61, as well as in the hose segments 51, 52 openings for the gas generator connector 59. Achieved by compressing these parts is a gas-tight sleeve connection 54. The discharge nozzles of the gas generator 47 are designated with 62, the release line for the gas generator with 63 and the guide brackets for the lines with 64. When assembling, first connected together via the sleeve joints 54 are the hose segments 50-53, and then screwed in are the gas generators 46-49, whereby, before screwing in the last gas generator the system is evacuated so that the hose system can be easily collected together into a small package in order to obtain a small volume system. This rapid inflation stabilizing system illustrated in FIG. 8-10 is therewith, in practice, constructively built up such that it can be incorporated as a complete, tested unit into the special parachute (SURVIVAL-AIR-GUARD). In this way it is replaceable within the total system.

The rapidly inflatable stabilizing system 31 can also be equipped externally to the hose seam, at functionally determined intervals, with brackets 65, in which are set easy-slip eyelets 66 through which are guided the ties 67 attached to the special parachute (SURVIVAL-AIR-GUARD), and that can be joined with this latter (see FIG. 9).

Furthermore, ties that loosely (with play) encircle the hoses of the stabilizing system can also be placed on the diameter of the special parachute (SURVIVAL-AIR-GUARD) on the inner side at suitable intervals in order thereby to allow the inflated system freedom of radial movement, so that different properties of expansion within the assembly will be equalized and damages in the operational condition will be avoided.

In another advantageous form of embodiment of the invention, the generator(s) is/are disposed within the stabilizing hose 31 (FIG. 11), where the gas generator is designated with 80, the dynamo (generator) for electrical ignition with 81, the igniter with 82, the distributor for the generators with 83, the seal with 84, the locking nut with 85 and the compression sleeve with 86.

Other geometric forms of the rapidly inflatable stabilizing system are also possible, where the positioning of the generators must be coordinated to the function of the stabilizing system.

It is significant that the round canopy/special parachute (SURVIVAL-AIR-GUARD) not be brought early into its form corresponding to its purpose only through the speed of flow and entry of air in free fall, but rather also with pyrotechnic support. Through this measure, the special rescue parachute (SURVIVAL-AIR-GUARD) has achieved its carrying and also its stabilized form, and its function is also therewith guaranteed at a lower jump height, about 30 m. Besides this, the stabilizing system generates a spring-back resilience effect in the direction of the arrow 68 and prevents a collapsing of the parachute, for example in the case of collision with buildings 38 caused by a shift in wind in the direction of the arrow 69 (see FIG. 12).

In accordance with FIGS. 13 and 14, the special parachute (SURVIVAL-AIR-GUARD) is also equipped with a harness (belt) system 70 that is in turn firmly joined with a vest 71. The vest 71 is attached to a carrier frame 120 (see FIG. 19) and is located on the front side of the survival case (SURVIVAL CASE), (on the side of the compartment 12 closed by the cover 15 a). Correspondingly, the parachute 30 is located on the backside of the center compartment 12, which is closed by the cover 15 b. At the same time, the parachute 30 is surrounded by a fire-resistant covering pack 73, whereby for use the parachute 30 is pulled out from the pack by means of a release line 110. Another possibility exists in the parachute 30 being catapulted out from the case/pack provided for the parachute with the aid of a supplementary gas generator, with the associated release mechanism also being actuated over the release line 110.

Alternatively, it is also possible that the vest with harness system be attached to the parachute case (container in which the parachute is folded together). The combination vest with harness system enables the rapid and safe deployment of the rescue system. The harness system cannot become twisted and makes deployment easier, especially in emergency and therewith associated stress situations.

The belts themselves are adjustable in length in relation to the person. In each case they are snapped into colored eyelets with non-interchangeable spring safety hooks 74 that are marked with like color. The vests are padded on the back and breast half and are made of fire-resistant material (like firemen suits). They are provided in all common standard sizes.

The third compartment 13 of the survival case (SURVIVAL CASE) 10 contains other survival tools and devices. For example, special hammer (survival crasher) 90, with handle for breaking glass panes (FIG. 13), breathing mask, dust mask, emergency bandaging equipment, cord/rope, two gloves 91, in each case for right- or left-handers respectively (FIG. 15), handyman's tool 92 (FIG. 16), adhesive tape, protective eyeglasses 93 with tiltable lamp 94 (FIG. 17) as well also as, under some circumstances, people-related utensils and materials.

The hammer 90 displays a cylindrical shape striker part 95 with a checkered pattern 96, an added forcing wedge 97 (wedge length about 5 cm, wedge angle about 16°), as well as a handle 98, where the cylinder diameter comes to about 30 mm. Attached to the handle 98 with a grip length of about 18 cm is a belt strap 99 that is preferably hooked with a spring safety hook 100 onto protective glove 91. The striker part 95 and forcing head part 97, as well as the hammer shaft 101 are made of stainless steel, while the handle is made of rubber. The hammer length 102 amounts to about 12 cm, the shaft 103 [sic] to about 28 cm, with the shaft diameter to about 18 mm. The weight of the hammer is about 750 grams.

The protective glove 91 displays an inside surface 104 made of leather and an outside surface made of a tear-resistant material. The leather thumb 105, in contrast to a usual glove, is not sewn to the inside surface 104, but rather along the edge 106, whereby the seam socket 107 is sewn in flexibly toward the front and rear so that there is no impairment relative to mobility of thumb in right or left hand usage. Moreover, placed on the outer surface as well as on the glove gauntlets 108 are reflective applications 109, in order, in case of darkness, to be able to better recognize the glove 91 with the associated hammer 91.

Guaranteed by the glove/hammer combination is that when breaking glass panes or the like the hammer can not slip or fly away, and the possibility of quick use and application is given for the right- and/or left-handers.

The 3-section survival case (SURVIVAL CASE), among other things, also has the advantage that by its variable construction it offers the possibility, by removal of the carrier frame 120 and the covers 15 a and 15 b, to directly combine into a 2-compartment case (see FIG. 18) the two outer compartments 11, 13 using the same adaptation locks, in which are now still found only the survival tools and equipment (without the special parachute.) This offers the possibility of equipping the survival case (SURVIVAL CASE) according to need. That is, for example, when the outside conditions clearly make recognizable in advance that only the breathing or smoke protection equipment, along with rescue tools, are needed, or possibly only the rescue parachute (SURVIVAL-AIR-GUARD). Through this possibility for variation, use of the life-saving device is also cost-favorably possible in targeted fashion.

The locking covers 14, 16, fitted on the outside compartments of the SURVIVAL CASE, can be furnished with emblems, symbols, pictures or even operating instruction texts. This can be done with posters, labels or also airbrushed on with a painting process.
